I have a Travel Poster from 1965 Abroad Ship Barbie Ensemble #1631 and I am trying to determine the value of it. Every poster I can find on the internet is a reproduction. I have compared the one I have to the reproduction and it has distinct differences so I am confident is it the original. I also have the original three travel brochures (Hawaii, Mexico, and Niagara Falls) and the How to Travel book. All of them are in great condition - no rips or fading.

Any help you can provide on determining the value of these items (especially the travel poster) is greatly appreciated. Thank you!
